Abstract: One disclosure in the present specification presents a method for a wireless device to receive a paging message. The method may comprise: a step of deciding a wake up signal occasion (WUSO) window for attempting to receive a wake up signal (WUS); and a step of monitoring a downlink control channel during a paging window so as to attempt to receive a paging message, if the WUS is received within the decided WUSO window. Here, the WUSO window may be decided according to a duration size and offset.

Abstract: One disclosure of the present specification proposes a method for receiving a Narrowband Reference Signal (NRS) by a Narrow band Internet of Things (NB-IoT) device. The method may comprise receiving the NRS on at least one or more orthogonal frequency division multiplexing (OFDM) symbols. The one or more OFDM symbols are in a time division duplex (TDD) subframe. If the TDD subframe corresponds to a TDD special subframe, the one or more OFDM symbols for receiving the NRS is determined based on which TDD special subframe configuration index among a plurality of TDD special configuration indexes is used by the TDD special subframe.

Abstract: This specification provides a method for performing early data transmission in a random access procedure in a wireless communication system.More specifically, the method performed by a user equipment (UE) includes: receiving, from a base station, a control message including first information indicating whether selection for a second transport size (TBS) smaller than a first TBS for message 3 is permitted and second information for the first TBS; transmitting, to the base station, a request for the EDT by using message 1; receiving, from the base station, message 2 including a UL grant for the message 3; determining a repetition number for the message 3 based on the control message and the UL grant; and transmitting the message 3 to the base station by the repetition number.Therefore, there is an effect that battery consumption of the UE can be reduced.

Abstract: The disclosure of the present specification provides a method for transmitting, by a user device, hybrid automatic repeat request (HARQ) positive-acknowledgment (ACK)/negative-acknowledgment (NACK) information. The method may comprise the steps of: determining a channel coding scheme to be used for transmitting the HARQ ACK/NACK information through an uplink physical channel, on the basis of first information; and performing channel coding of the HARQ ACK/NACK information according to the determined channel coding scheme. The channel coding scheme may include at least one of a channel coding scheme, a cyclic redundancy check (CRC) architecture, a channel encoder size, and a modulation scheme.

Abstract: The present invention relates to a wireless communication system and, specifically, to a method comprising the steps of: repeatedly transmitting a PUSCH; and repeatedly receiving the PDSCH in a DL duration immediately following after repeated transmission of the PDSCH, wherein when a terminal operates in an in-band mode, each PDSCH is received from an OFDM symbol subsequent to a k-th OFDM symbol in each corresponding time unit within the DL duration (k>1), and in the case where the terminal operates in a guard-band mode or a stand-alone mode, signal reception is skipped at a starting portion of the DL duration when the PDSCH is repeatedly received.
